I think some people complained about the switch being to easily accidentally activated so lumenstop redesigned it to make it even worse :laughing:
For me, I don’t notice the change in activation much but it feels a lot better. I love the SST20. I don’t have a xpl-hi version. Everybody says it’s hotter. Does that mean you can hold the xpl an extra 10 seconds on turbo or at the top of the ramp? What are we talking about here in real terms?
The one I had ,10 seconds would’ve been a luxury.
Comparing my first units & this one…. that is exactly what happened Nev. :person_facepalming: . 
Maybe the design requires higher precision that is possible at this price point? I don’t know, just wondering. On a related note, who creates the blueprint files for projects like this?
Nev, there’s no ugly green tint from your example sst20 ?
I had XPLHI , after a short time it did develop a blue tinge to it, but that was after one led went bad & started to smoke , but before that it was ok for a warmish or neutral or whatever just under 5000k is ,with no green more of a yellowy white.
Another new colour I’ve invented
Never heard of that happening before. XPL-HI is normally extremely tolerant of hi current.
LOL… too bad they aren’t using XPL HI V4 3C 5000k yet… I hear it’s a nice rose tint, no yellow
It wasn’t the led that was smoking (it was just discoloured) the smoking was from the negative black wire which got hot enough to melt the solder & disconected itself , the smoke was coming from the plastic insulation on that wire.
Probably could take q-tip wipe off residue?
Still… bet when u saw smoke made ya pucker a little lol
That shouldn’t have happened either. I wonder if maybe the star needs new thermal compound underneath.
I was taking a video to show neal the smoking & as luck would have it that’s when it melted the solder & disconnected itself ,I could smell it was hot just like a D4 or any other high power light gets , but this was a burning smell & that’s what made me take the bezel off to see where it was coming from.
It had some on but only a very thin layer. I’m not a modder so I can’t say if it was enough.
He took the bezel off so the star was not actually pressed into the head. The star got way too hot with no way to transfer the heat.
Lumintop does all the blueprints.
That would do it. The star on the FW3A isn’t screwed down. If you ran it for more than a few seconds on turbo without the bezel on, the star could very easily overheat.
Yes he did but it was burning & or smoking before the bezel was taken off , I could smell burning so I took the bezel ,optic ,lens off to see where it was coming from.
Your on a roll mate…. keep it up!! 
I’m guessing one of the Leds was not flowed on well and it wasn’t transferring the heat like it should. It’s important that the center pad under the led, the thermal pad, is soldered properly. This made the one led turn blue and start burning/smelling. Then removing the bezel and going Turbo really fried things. So a pretty rare chain of events and not something that happens often. Normally the XPL are tough and can handle more current than the FW3A can produce.
